Re: Benchmarking for SVN?

I had a benchmarking framework a while I used to compare SVN vs P4 vs CVS.

http://subversion.kicks-ass.org/perfnew/elapsed.html

The hard part about making a benchmark that runs over an extended period
of time is that the results aren't very useful if the machine you are
running doesn't get locked down. Things like the kernel, filesystem
free disk space, etc all affect performance and may skew the results
beyond usefullness.

Maybe a slightly better approach would be to do something in the line of
a CMake like build status page that has these benchmarks built in.
While not very useful by themselves, you can detect problems if suddenly
one platform gets much slower than the others by looking at the averages.
